Some eight or ten miles behind us, however, there stretched as far as the eye could reach a range of precipitous hills that formed a retaining wall of the lake, and I have no doubt but that it was through some entrance in these hills that the subterranean river found its way into the open water.

Indeed, I afterwards ascertained this to be the fact, and it will be some indication of the extraordinary strength and directness of the current of the mysterious river that the canoe, even at this distance, was still answering to it.

Presently, too, I, or rather Umslopogaas, who woke up just then, discovered another indication, and a very unpleasant one it was.

Perceiving some whitish object upon the water, Umslopogaas called my attention to it, and with a few strokes of the paddle brought the canoe to the spot, whereupon we discovered that the object was the body of a man floating face downwards.

This was bad enough, but imagine my horror when Umslopogaas having turned him on to his back with the paddle, we recognized in the sunken features the lineaments of -- whom do you suppose?
None other than our poor servant who had been sucked down two days before in the waters of the subterranean river.
